+# krm-fn-kustomize
+
+[KRM](https://github.com/kubernetes-sigs/kustomize/blob/master/cmd/config/docs/api-conventions/functions-spec.md) function
+to run [Kustomize](https://kustomize.io/).
+
+## Usage
+
+By default this function will build the Kustomization and output it to `build.yaml`.
+
+```shell
+kpt fn eval --image ghcr.io/jashandeep-sohi/krm-fn-kustomize
+```
+
+You can override the kustomize command using the `cmd` option:
+
+```shell
+kpt fn eval --image ghcr.io/jashandeep-sohi/krm-fn-kustomize -- cmd='kustomize build --output test.yaml'
+```
+
+Or declaratively:
+
+```yaml
+apiVersion: kpt.dev/v1
+kind: Kptfile
+metadata:
+  name: example
+  annotations:
+    config.kubernetes.io/local-config: "true"
+pipeline:
+  mutators:
+
+  # This will build the Kustomization and output it to build.yaml
+  - image: ghcr.io/jashandeep-sohi/krm-fn-kustomize
+
+  # Override the command
+  - image: ghcr.io/jashandeep-sohi/krm-fn-kustomize
+    configMap:
+      cmd: kustomize build --output test.yaml
+```
